Ojbectives This study aimed to investigate whether thoracic skeletal muscle mass index at the diagnosis of aspiration pneumonia is a predictor for the recurrence of aspiration pneumonia and to explore predicting factors for the recurrence of aspiration pneumonia in stroke patients with dysphagia disorder. Methods We retrospectively reviewed the data of patients with aspiration pneumonia who diagnosed with dysphagia disorder due to stroke from Jan. 2014 to Jul. 2020 in The Catholic University of Korea Bucheon St. Mary’s Hospital. Aspiration pneumonia was defined based on clinical signs of symptoms suggestive of pneumonia and radiologic findings of pneumonic infiltrations in the dependent portion of lung. We measured thoracic muscle volume by using the cross-sectional area (CSA) of the erector spinae muscle (ESMCSA , cm2) at the 12th vertebral region. CT scans at the time of diagnosis of aspiration pneumonia were used for analysis and respective CSA were divided by height squared (m2) to yield the muscle index at T12 (T12MI, cm2/m2) to normalize for stature. Multivariate logistic regression models were performed to investigate relationships between clinical parameters and recurrence of aspiration pneumonia. Results During study period, a total of 268 stroke patients with dysphagia disorder and developed aspiration pneumonia were analyzed. Mean T12MI of patients with and without recurrence of aspiration pneumonia was 708.1±229.9 cm2/m2 and 622.3±184.1 cm2/m2, respsectively (P=0.001). Multivariate logistic regression revelaed that lower T12MI (P=0.038) and older age (P=0.007) were the independent predictor of recurrence of aspiration pneumonia in stroke patients with dysphagia disorder. Conclusion Low thoracic muscle index at the diagnosis of aspiration pneumonia predicts recurrence of aspiration pneumonia in stroke patients with dysphagia disorder.
